COMPANY, INCORPORATED, A CORPORATION OF DELAWARE s'roxnn, comm Application med October a, 1930. Serial No. 486,095.

This invention relates to conveying mechanism and more particularly to fuel conveying mechanism for a locomotive stoker in which fuel is conducted from a source of supply, as from a tender to the firing opening in the backhead of a locomotive in the most direct course consistent with permissible obstruction of the space behind the backhead and above the firing deck, and so conveying w the fuel with a minimum of crushing or breaking down of the fuel. V

llhe rincipal object of the invention is to simpli y, lighten and improve the eficiency of" transferring mechanism for conveying fuel from the fuel bin of a locomotive tender to a point of discharge into the firebox of the locomotive Other and further objects and advantages will appear from the following description 2% taken in connection with the accompanying drawings, in which Fig. 1 is a longitudinal vertical section of a portion of the locomotive and tender, showing the invention in position thereon;

Fig. 2 is a plan view thereof, with parts broken away and parts in section.

Referring now to the drawings, the locomotive is indicated enerally at 10, and is provided with a firedioxll having an upstanding rear wall 12 with a firing opening 13, therethrough. The locomotive 10 is provided with the usual deck 14, and the tender shown at 15 is provided with a floor 16 having a fuel 0 emng 17 therethrough for supplying fuel by gravity to the trough portion 18 of the transfer conduit 19 as is usual in such constructions.

The tender 15 includes a fuel bin 20 e uipped with the plates 21 slidably mounte in the opening 17 and by moving the plates 21 the delivery opening may be shifted to suit conditions.

The transfer conduit ;.19 comprises the trough portibn 18 and lie tubular extension 20 leading forwardly rom the'trough portion 18 and then bent upwardly. extending toward the firing opening. The transfer conduit 19 is forined of a single casting thereby eliminating a joint at the bend in the conduit providing a rigid, durable, simple and economical construction. The forward end of the tubular extension 20 has formed therewith a ball member 22 cooperating with a horizontally split spherical flange 23 on the rear end of the fixed conduit 24 to form a flexible connection between the conduits.

The transfer conduit 19 is supported beneath the opening ,17 by rollers 25 on the rails 26 whereby the conduit may move longitudinally of the rails and may have a slight angular movement to provide for articulation between the locomotive. and tender.

The fixed conduit 24 is carried from the backhead or rear wall 12 by the bracket 27. The front end of theg fixed conduit delivers directly to the firing 'opening and onto a distributor plate 28 in the path of a pressure fluid blast issuing from a nozzle 29. The front end of the fixed conduit is formed by a separable hood or mouth member 30 which at its rearward end is attached to the main section of the fixed conduit as by bolts through the flanges 31, 32, and at its forward end is rigidly secured to the backhead 12 in communication with the opening 13 by a suitable fastening means through the laterally extending flanges 33, 34. The side walls of the hood member flare laterally to permit a spreading of the fuel as it is delivered to the distributing means.

The distributor plate 28 is detachably connected to an upright wall of the hood member 30 by bolts as at '35, and forms an extended floor portion of the conduit which projects through the firing opening 13 of the backhead. The nozzle 29 is vertically disposed rearward of the distributor plate and pressure fluid such as steam is supplied thereto by a suitablenumber of supply pipes 36.

Fuel is advanced through the transfer conduit 19 and the fixed conduit 24 by a sectional conveyor comprising the screws 37 and 38 in the transfer conduit 19 and thescrew 39in the fixed conduit 24. The screws 37 and 38 are flexibly connected by the universal joint 40 adjacent the bend in the transfer conduit and the screws 38 and 39 are flexibly connected by the universal joint 41 adjacent the communicating ends of the transfer and fixed conduits.

Suitable means is provided for Operating a screw in said rigid conduit flexibly conthe sectional screw conveyor. ismounted on the tender and operatesthe s sectional screw conveyor from the rear end thereof by the 'angularly arranged extensible telescoping'power shaft 43 through the spur gears 44 and 45; see Fig. 2. The wer shaft 43 is provided with universal joints 46 and 47 at its end portionsfor accommodatingits angular position relative to the motor and the gears.

In operation, fuel passes by gravity through the opening 17 in the floor of the tender into the trough portion 18 of the transfer conduit 19. The fuel is moved forwardly by the screw 37 past the crusher 48, which reduces the oversize lumps, and through thetubular extension 20 by the screw 38, and then through the fixed conduit 24 by the screw 39 to the plate 28 over which it is swept by jets and thus distributed in the firebox.

It will thus be apparent that the fuel is positively conveyed in a very direct path from the trough to the firing opening by a novel conveying system which is simple 1n construction, cheap to manufacture and very I eflicient in operation.

I claim:

1. In a locomotive, provided with a backhead having a firing opening therein, and a tender, a fuel conveying system comprising a conduit fixed rigidly to said backhead and communicating with said firing opening, a unitary transfer conduit movably mounted on the tender having an upwardly inclined forward portion and universally connected at its forward end to the rearward end of'said fixed conduit, .a screw in the rearward portion ofsaid transfer conduit, a screw in the inclined forward portion thereof, said screws being flexibly connected adjacent the bend in 'said transfer conduit, and a screw in said i I fixed conduit flexibly connected at its rearward end with the screw in said inclined forward transfer-conduit portion.

2. In a locomotive, provided with a backhead having a firing opening therein and a cab deck, a tender having a floor, a fuel cona conduit rigidly communicating at its forward end with said firing opening and extending rearwardly and downwardly thereveying system comprising 3 from and terminating below said cab deck,

a continuous transfer conduit movably mounted on the tender extending horizontal 1; forward beneath the floor of the tender and having its forward portion bent upwardly from the horizontal and flexibly connected at its forward end to the rearward end of said rigidly mounted conduit, a conveyer screw in said horizontal transfer conduit portion, a conveyer screw'in said-upwardly bent portion, said screws being flexibl connected ad- ]acent'the bend in said trans er conduit, and

A motor 42 nected at its rearward end with the screw in aid upwardly bent transfer conduit portion. In testimon whereof I aflix m signature.
